To @ZZ whom t 'may concern:

Be it known that I, ALBERT A. GORDON, Jn., a citizenof the UnitedStates, residing at Worcester, in the county of Worcester and State ofMassachusetts, have inventedL a new and useful Veft-Replenishin'g Loom,of which the following is a specification.

This inventionrelat'es to 'a weft replenishing loom of the so-calledterrytype in which a looped uncut pile is' formed by.

varying the forward positionofthe reed as different picks" of weft orfilling are beaten'into the fabric.

More specifically,'l my invention relates to a loom of this typein whichthereed is fixed in the lay and the forwardv position oftheentireassembly of lay and reed is variedV on different beats Vof thelay.y

It is the Vobject of myinvention toprovide a weft replenishing mechanismfor a loom of this type so mounted and'actuated that it' will alwaysmaintain its operative relation in respect tol the layy and' to 'theshuttle`and shuttle boxes thereon. i

For the attainment of this object, my improved magazine is movably`mounted on. the loom frame andV ris vso connected with the terrymotionthat the position of the 1 magazine is changed to correspond tothe forward or rearward adjustment of the lo# cus of the lay movement.

In the 'preferred form of my invention not only the magazinev butcertain other A parts of the weft replenishing mechanism such. as theweft detector l'and the thread holder are also mounted to move as a unitwith the magazine as the latter is vaiably positioned.

My invention further relates to arrangements and combinations of'partswhich will beherelnafter described and more particularly pointed out inthe appended claims.

A. preferred form of' my invention is shown in the drawings, in which-Fig. 1 isa sideelevation'of parts of a loom embodying my improvements;

Fig. 2 is a detail 4sectional view taken along the line 2-2'in.Fig. 4'1;

Fig. 3 is a front elevation of my improved magazine and the supportstherefor;

Fig. 4 is a detail rear elevation looking in the direction of the arrow4 in Fig. 1; and

Fig. 5 is a detail side elevation looking in the direction of the arrow5 in Fig. 3.

Referring to the drawings, I have shown parts of a loom which are ingeneral of the usual terry type comprising a loom frame 10, an'arfoh 11,and a lay 12 mounted on swords 13 which swing about fixed pivots, notshown. The lay is Imoved forward and rearwar'din the usual .manner byconn'ectin pins 15in a crankshaft 16.l

The bearing :for the 'shaft 16 are eccentri-y callyfpositioiied fin`ycylindrical bearing blocks 17 rotatablymou-nted.` in 4journal boxes 18.n arm' 19 is fixed to each bearing block 17 and is connected by 'a 'link20 to an arm 21 fixed on a cross shaft 22. An actuatingiarm 23 alsofast: on the'shaft v22 is 'connected'by g 'rods 14 actuated fromv "cranka tlink 24 to -a'stud 25 in a lever 26. *The lever "26 is pivotedat 27to across girt 28 and is periodically moved downwardbyengagementf'w'ith'a `roller 29 on an arm 30.

" The arinBO. rotates with la gear -31 driven by-'a pinion 32 on theusual bottom or cam shaft 33 of the loom.l `As shown in 'the drawings,the gear 31 and pinion 32` are inthe size relation o'f threey to two.yAs the bottom shaft ,3-3 rotates onceJ for every two beats of the lay,the lever 26 will v.be depressed once for 'everythree'beatsof the `'Itwill-be. understood, however, that. the gearing. ratio. maybeA varied toproduce` a movement of the lever 26l once yinany desired number of beatsof the lay. The-parts are shown in Fgl with therleverf' depressed andthel'ay. in its extreme forward position,` the parts assuming thisposition o1revery'thrd-beatfof ,the lay.

y"The parts .thus far described, are of the usual type and-formino partof my present 5 nventQm which relates particularly tothe, weftreplenishing mechanism and to the provision 'of means by which it may bemaintained in' operative' relation to the .n lay,

whether the. samey is forwardly or rearwardly positioned. f

f A weft carrier 'magazine y85 of the usual type for'multi-color ,workis shown in the '.f

drawings, the magazine eomprisinga maga'- zine frame 36, an outerbobbinsupport 37," a thread holder 38, a transferrer 39 and other usual partsassociated therewith. A link 4) (Fig. l) is connected to a bell crank 41pivoted at 42 on the magazine frame and connecting the bobbin releasingdevices with the usual drop box mechanism. not shown.`

For a detailed description of the magazine and its connection to thedrop box mechanism, reference is made to the prior patent to Wyman No.970,591 issued September 20, 1910.

The magazine frame 36 is in part supported upon a slide 43 (Fig. 3)mounted in a block or guide-way 44 bolted to the front of the loom framelO. The slide 43 is preferably lofthe dove-tailed section shown in Fig.3

and suitable provision is made for maintaining a close sliding t betweenthe parts. A second slide 45 (Figs. 1 and 2) is mounted to slide in aguide-way or block 46 irmly secured to the loom arch 11.

An actuating lever 48 (Figs. 3 and 5) is mounted on a fixed pivot 49 andthe forked upper end of the lever 48 engages the elongated end of theshaft or stud 50 upon which the transferrer 39 is pivoted. The lever 48is connected by an adjustable link 51 to an arm 52 secured to one of thecylindrical bearing blocks 1T which support the crankshaft 16.

Through these connections, the lever 48 will be swung on its pivot 49whenever the bearing of the crankshaft 16 is moved forward or rearward,and a corresponding forward or rearward movement of the magazine 35 willoccur. The magazine 35 is thus always positioned in co-operativerelation with the shuttle S in the shuttle boX 53 (Fig. l), the magazinemoving-forward or rearward whenever the locus of movement of the lay isshifted forward or rearward. A weft carrier transfer may thus occur onany beat of the lay provided the desired shuttle S is in the box 53.

I have also-provided weft detecting mechanism of a usualv type, mountedupon' a bracket 54 secured by bolts 55 to the magazine frame and movableforward and rearward therewith. The weft detecting member 56 (Fig. 1)-is thus maintained in operative relation with the shuttle in either theforward or rearward adjustment of the lay.

I have thus provided simple and reliable mechanism for maintainingoperative relations between the lay and thevmagazine and partsassociated therewith, regardless of changes in the locus of movement ofthe lay, so that weft carrier transfer will not be subject tointerference from such changes in adjustment.

In the specification and claims the term locus of movement is used toindicate the limits of movement of the lay when the lay is oscillatedand the bearings remain in some fixed position. When the bearings aretions can be made therein by those skilled in the art within the spiritand scope of my invention as set forth in the claims, and I do not wishto be otherwise limited to the details herein disclosed. but what Iclaim is 1. In a loom, a lay, means `to shift the locus of movement ofsaid lay forward and rearward, a loom frame, a weft replenishingmechanism movably Lmounted thereon, and means to move said mechanismforward and rearward to maintain the same in operative relation to saidlay.

2. In a loom, a lay, meansv to shift the loc-us of movement of said layforward and rearward, a loom frame, a weft replenishinff mechanismmounted to slide thereon, an means to slide said mechanism forwarderrearward as the locus of movement of the lay is shifted.

3.v In a loom, a lay, means to shift the locus of movement of said lay,a loom frame, a weft replenishing mechanism movably mounted thereon, andconnections from said magazine to said lay-shifting means by which saidmagazine may be shifted forward or rearward to correspond with a changein the locus of movement of the lay.

y4. In a loom, a lay, means to shift the locus of movement of said layforward or rearward, a weft .detecting device, and means to maintainsaid detecting device in operative relation to said lay in all positionsofthe locus of movement thereof.
